The invention relates to the technical field of underwater power propellers, and particularly relates to an electromagnet and permanent magnet combined vector magnetic coupling propeller. As the types and operation types of underwater robots, ships and the like are more and more, the performance requirements of the underwater propellers are higher and higher, underwater equipment is soaked in water for a relatively long time, if the sealing performance of an underwater propeller is not good, equipment faults can be caused, underwater equipment cannot work normally, the service life of the underwater equipment is shortened, and the underwater permanent magnet coupling propeller for converting dynamic sealing into static sealing has the problems of low transmission efficiency, insufficient transmission power, single transmission power direction and the like due to the fact that a gap between inner and outer rotors is too large. In order to overcome the defects in the prior art, the electromagnet and permanent magnet combined vector magnetic coupling propeller suitable for underwater power vector propulsion is provided, magnetic coupling vector propulsion is achieved through the steering engine, and a gap energy loss generated during magnetic coupling vector propulsion is compensated through the electromagnets.
本申请涉及水下动力推进器技术领域,特别是涉及一种电磁永磁结合的矢量磁耦合推进器,随着水下机器人以及船舶等的种类和作业类型越来越多,其对水下推进器方面的性能要求越来越高,水下设备在水中浸泡的时间相对较长,若水下推进器的密封性不好则会引起设备故障,导致水下设备无法正常工作,缩短水下设备使用寿命,将动密封转化为静密封的水下永磁耦合推进器存在由于内外转子间隙过大造成传递效率低、传递动力不足、传递动力方向单一等问题。本发明针对现有技术的不足,提供一种适用于水下动力矢量推进的电磁永磁结合的矢量磁耦合推进器,通过舵机实现磁耦合的矢量推进,通过电磁铁实现对磁耦合矢量推进时产生的间隙能量损失进行补偿。
